Jacob Handyman has been told that 50 identical bolts and 20
identical nuts cost \$9.10, whereas 30 nuts and 40 identical
washers cost \$4.00. If 10 each of bolts, nuts and washers cost
\$2.70, what is the price of each washer?

You will have to formulate 3 equations and solve them

Let bolts be b, nuts be n and washers be w.

From the first statement,

50b + 20n = \$9.10

Similarly from the next statements,

30n + 40w = \$4.00

I would like you to try to formulate the last equation as
practice, okay?

The answer should be 4 cents.
